DEMO is a fusion power plant planned for the year 2040, which will feed electricity into the public grid for the first time. Like ITER, DEMO will also follow the Tokamak principle. The neutron radiation produced during nuclear fusion leads to severe damage of the reactor materials, which necessitates regular replacement of the damaged components. For this reason, maintenance phases are necessary. The duration of these maintenance phases is decisive for the economic efficiency of such a fusion plant. Due to the radiation exposure, almost all processes must be carried out remotely. We are involved in the design and construction of components for remote control applications such as the Contamination Control Door (CCD) and Mechanical Pipe Connection (MPC). Through the description, modelling and simulation of the maintenance process logistics, control strategies are examined and optimization potentials are identified.
